| Summary | The Genmax GM6250iET is a 5,500-watt tri-fuel inverter generator built for users who need substantial backup power without sacrificing electronics protection. Its 3% THD rating means it can safely power laptops, refrigerators, and air conditioning units simultaneously, while the tri-fuel capability lets owners switch between gasoline, propane, and natural gas depending on availability. This combination of clean power and fuel flexibility makes it a practical choice for RV owners, homeowners facing extended outages, and job sites where power quality matters as much as raw wattage. | The Predator 73422 is a gasoline-powered generator rated for 2000 running watts with 2500 starting watts. That combination sets it up to handle steady electrical loads while also giving extra headroom for devices that draw more power when they first switch on. |
